 Can  you tell me what has happened to this FAQ? I need to know the answer and I can't find it on the wiki, tbh I find navigation the documentation quite difficult and finding what I want more so.

 re faq: Someone changed it :).. sorry :(

re ports: Only port 80 is supported.  there was talk a long time ago about maybe opening up more, but it didn't happen. :) 

 Limiting to only port 80 makes it extrememly difficult to test things if you don't want to go live and want to try things out on test machines that are not normally accessible on a publicly accessible machine. For all Facebook development I can create and SSH tunnel from a live machine to my laptop here to get immediate changes visible on my test app without having to haphazardly publish it all the time.
